It can be understood that, during the process of stepping down the pedal 210, the one-way bearing 900 is in the engaged state, at this time, the driving shaft 21 can drive the transmission portion to rotate and compress the first torsion spring 25, and then when the pedal 210 is lifted up under the elastic force of the first torsion spring 25, the one-way bearing 900 is in the disengaged state, at this time, the transmission portion cannot rotate along with the reset of the driving shaft 21, so that the pedal 210 on one side of the pedal 210 is continuously stepped down to adjust the one-way movement of the fixing component 5.

In this embodiment, as shown in fig. 3, 4 and 6, the transmission part includes a transmission shaft 22, a first bevel gear 211 and a second bevel gear 220, wherein the transmission shaft 22 is rotatably connected to the second rotating base 120 disposed on the side wall of the side plate 12, the second bevel gear 220 is fixedly mounted at the lower end of the transmission shaft 22, the first bevel gear 211 is connected to the end portion of the driving shaft 21 close to the side plate 12 through a one-way bearing 900, the first bevel gear 211 and the second bevel gear 220 are engaged with each other, the upper end of the transmission shaft 22 is engaged with the screw shaft 24, and the rotation angle of the driving shaft 21 can be reversed through the first bevel gear 211 and the second bevel gear 220, so that the pedal 210 is stepped to drive the supporting plate 3 to move upwards.

It can be understood that, during TEP surgery, the elevation space height adjustment of the peritoneal wall is often several millimeters, and in order to ensure the accuracy of the surgery, it is necessary to ensure that the single adjustment stroke of the fixing assembly 5 is small, so that the rotation angle of the driving shaft 21 needs to be adjusted through the first gear set 23, so that the single stroke of the height adjusting mechanism 2 meets the requirement.

In this embodiment, the operation principle of the two-side height adjusting mechanism 2 is as shown in fig. 13, when the pedal 210 of the left-side height adjusting mechanism 2 is stepped on, the screw shaft 24 on the left-side height adjusting mechanism 2 can be driven to rotate counterclockwise through the transmission part and the first gear set 23; when the pedal 210 of the right height adjusting mechanism 2 is stepped on, the transmission part and the first gear set 23 can drive the screw shaft 24 on the right height adjusting mechanism 2 to rotate clockwise to drive the support plate 3 to move upwards, and in the process of moving the support plate 3 upwards, the sliding part 320 on the right side of the support plate 3 can drive the screw shaft 24 on the right height adjusting mechanism 2 to rotate clockwise, so that the one-way bearing 900 on the right height adjusting mechanism 2 is in a separated state, that is, the drive shaft 21 of the right height adjusting mechanism 2 is relatively static; similarly, when the pedal 210 of the right height adjustment mechanism 2 is stepped on, the right screw shaft 24 rotates counterclockwise to drive the support plate 3 to move down, and during the process that the support plate 3 moves down, the left sliding portion 320 drives the left screw shaft 24 to rotate counterclockwise, so that the one-way bearing 900 on the left height adjustment mechanism 2 is in a separated state.

In one embodiment of the present application, as shown in fig. 1, fig. 2, fig. 7 to fig. 9 and fig. 14, an adjusting gear 511 is fixedly mounted at a lower portion of the connecting sleeve 51, the angle adjusting mechanisms 4 are respectively mounted at left and right sides of a front portion of the supporting plate 3, the angle adjusting mechanisms 4 include a driving rod 41 and a second gear set 42, a front end of the driving rod 41 is rotatably connected with the supporting plate 3 through a fixed rotating shaft 411, a second torsion spring 43 is sleeved at a lower portion of the rotating shaft 411, two ends of the second torsion spring 43 are respectively connected with the supporting plate 3 and the rotating shaft 411, and the other end of the driving rod 41 extends to a position above the pedal 210; the second gear set 42 is rotatably connected to the support plate 3 through a one-way bearing 900, and the front end of the driving rod 41 is engaged with one end of the second gear set 42 through a sector gear 410 fixedly connected to the front end, and the other end of the second gear set 42 is engaged with the adjusting gear 511. Thereby when the doctor need adjust the position about the peritoneum wall space in the operation, the position direction that can adjust as required, promote the actuating lever 41 of one of them side through the shank and rotate, then actuating lever 41 drives second gear set 42 through the sector gear 410 of front end and rotates in order to drive adjusting gear 511, and then realizes the clockwise rotation or the anticlockwise rotation of fixed subassembly 5, and through continuously promoting actuating lever 41, can drive fixed subassembly 5 and continuously carry out clockwise or anticlockwise rotation, until obtaining required peritoneum wall space position.

It can be understood that, during the process that the driving rod 41 on one side rotates towards the side direction, the one-way bearing 900 is in the engaged state, at this time, the driving rod 41 can drive the adjusting gear 511 to rotate and compress the second torsion spring 43 by driving the second gear set 42, and then, when the driving rod 41 performs the reset rotation under the elastic force of the second torsion spring 43, the one-way bearing 900 is in the disengaged state, at this time, the adjusting gear 511 does not rotate along with the reset of the driving rod 41, so as to realize the one-way rotation that the driving rod 41 on one side is continuously pushed to adjust the fixing component 5.

In this embodiment, as shown in fig. 7, 9 and 14, the second gear set 42 includes at least a pair of gears, for example, as shown in fig. 7, the second gear set 42 includes three gears, which are a fifth gear 421, a sixth gear 422 and a seventh gear 423.

It can be understood that, when the TEP operation, the position is often several millimeters about the lifting space of peritoneal wall is adjusted, in order to guarantee the accuracy nature of operation, it is less to guarantee the single regulation stroke of fixed subassembly 5, so need come to adjust the turned angle of actuating lever 41 through second gear set 42 to make the single stroke of angle adjustment mechanism 4 satisfy the demand.
